TVS - Diodes are a particular type of semiconductor device, designed to protect voltage sensitive components or circuits from electrical overstress caused by sudden surges such as lightning strikes or high energy electrostatic discharges (ESD). UPT28R/TR13 is an example of such a diode, which is a transient voltage suppressor with a breakdown voltage of ± 28 V. It features small size, low leakage current and fast response time, making it suitable for a wide range of protection applications.

The UPT28R/TR13’s operation is based on the principle of semiconductor breakdown, or Voltage Breakdown. When applied to a p-n junction diode, the passage of current through the junction causes the depletion region – the space between the n-type and p-type layers – to get wider and deeper as a large electric field is created in the depletion region. When this electric field exceeds the diode’s breakdown voltage, the depletion width gets too wide, causing the diode to break down and allowing current to flow freely through it.

Due to its small size and fast response time, the UPT28R/TR13 is well suited for a variety of applications including voltage regulation, circuit protection, ESD protection and surge protection. It is commonly used in portable electronics, such as mobile phones and tablets, as well as in automotive electronics, telecom equipment, industrial equipment and military systems. It is also used in the aerospace industry, where it can be used to protect circuits and components from the intense electrical fields produced by lightning and solar flares.

The UPT28R/TR13 is a two-terminal device that can be connected directly to the system or circuit being protected, without any additional components. For most applications it is recommended that the diode be connected to the signal path in series. This is done by connecting one terminal to the node being protected and the other terminal to ground. The diode will then act as a clamp, providing protection against both positive and negative voltage surges.

The UPT28R/TR13 is an effective and reliable solution for protecting circuits and components from electrical overstress. Its small size and fast response time make it an ideal choice for a variety of applications, from portable electronics to aerospace applications. It is a low-cost solution to the problem of ESD and surge protection, and is capable of providing reliable protection for even the most sensitive circuits and components.
